PAPERf-SORTNG MACHINE.

To all lwhom it may concern:

Be it known that I, GEORG Spiess, a. subject of the Emperor of Germany, .residing at -Leipzig-Reudnitz, Saxony, have invented new and useful Improvements in P aper- Sorting Machines, of which the following 1s a specification.

The present invention has reference to improvements in paper sorting machines, and relates more specifically to means in connection with the ordinary machines for rougli-sorting or grading. sequentially fed sheets of paper, for additionally fine-sorting the paper in regard to color shades, d oublings, creases, and the like irregularities; and the invention essentially consists of a special, partly manually and partly automatically actuated, device for throwing out any sheet defective in the above indicated respect, and for properly piling the defective sheets. i

In the paper sorting machines now in use the sheets, separated singly from a banky of sheets, are first freed of scraps and the like by a wiping or brushing device; they are then passed over an inspection table and finally piling. This pre-sorted pile is then manually sorted over again for lesser defects.

It is the special purpose of the present inf vention to produce a machine in which this additional sorting by manual laborv also is effected in the machine whereby a prac tically useful sorting machine is provided. This has been primarily attained by providing between the first course of observation and the end of the piling table an additional course of observation over which the roughly sorted sheets, after being freed of the sci-aps are passed for the purpose of effecting a finer sorting ofthe sheets so that the sheets not coming up to the standard are separated and piled to be usedl for special 'purposes where standard sheets are not required. I y

In order to make this invention more readily understood, I will now describe it in detail with reference to the accompanying y drawings, in whichz.

Figure 1 represents a diagrammatic front elevation of the complete machine; Fig. 2 shows a plan thereof; Figs. 3, 4 and 5 represent front elevations of the sheet ejecting mechanism proper 4in different operative positions.

` Specification of Letters Patent.

Application led J'uly 14, 1915. Serial No. 39,814.

The invention is to be employed in connection with a machine having preliminary sorting means at one end and stacking means at the other end.

' According to the present invention, immediately after having been thus mechanically cleaned, those sheets Which have defects .in coloring or other irregularities, or in any other way do not come up to the standard, but which can still be used for other purposes, are passed above an intermediate pile table 13 and are dropped thereon. The perfect sheets arecarried on by the griplpeis and are ina'lly deposited on the pile tab e 21 In this manner the sheets 'are perfectly sorted and graded, and the defective sheets are at once properly piled by themselves, thus saving all after-sorting and repeated handling.

In order to render it possible to use the pile table 13 for sheets of varioussizes this pile table has on its front sheet supporting means so that the sheets freed from scraps always restk yagainst the same stops of this pile table.

In the Figs. 3-5 is shown, on an enlarged scale, the mechanism for ejecting the defective sheets. A cam disk F is continuously rotated in suitable :manner and intermittently actuates the rock lever '0, the roller U of which contacts with the cam disk.l A spring R tends to retain theparts in operative contact. To the upper end of' this rock lever a bar or` rod G is pivoted with one end while its other end is pivoted to the one arm of a bell crank lever H, to the other arm of which is linked the link C. When the hand lever is depressed,

the locking arm D is raised and the rock lever O is freed.

The operation of the machine is as'follows z--When a defective sheet passes the vintermediate point of observation, the operator depresses the hand lever A; the correspondingly raised arm W is then locked in the upper end-position iii any suitable manner, for instance by a spring catch E, the

locking lever D is lifted (Fig. 4) and the 1 ,drops into the recess in the disk O, the bar or rod G is pulled downwardly and the grip tripper K is moved into the ath of the traveling gripper L, causing e latter to open and to release the sheet, whichthen drops unto the pile table 13. To the, rock lever O is further linked a bar or rod yM to the free end of which is pivoted the pawl P which coperates Withthe ratchet Wheel .X,`

through which the geartrain for adjusting the support S for the pile table 13 is actuated.

When the sheet has been deposited, the rock lever O is oscillated back to its initial position (Fig. 3) and all other parts also resume their initial position. lever A, whose arm Y is linked to the rock lever O by. means of'a connecting rod B with lost motion at Z, is automaticall vshifted back again into its ino erative posltion, and simultaneously the ocking lever D iis dropped into the position where it locks' the oclkx lever against being operated by the cam What I- claim is 1. In a paper sortin machine, an intermediate sorting and pi ing device comprising a course of observation a pile support mediate sortin The hand with mechanism coactin `therewith for selecting, separatin an pilin imperfect sheets of paper inc uding manu ly operated means for actuating the said mechanism.

2. In a paper sortin machine, an interandpi ing device comprising a course o observation with mechanism for selecting, separating and piling .im-

perfect sheets of paper, a device formanually starting the jmechanism for. ejectng the defective sheets, and means for automatically operating and locking the same.

3. In a paper sortin machine, an intermediate sorting and pi ing device comprisinga course'of observation with mechanism for selecting,l separating and piling imperfect sheets of paper, a hand lever for manually starting the mechanism for lejecting the imperfect sheets, means for automatically operating and locking the same,

a pressure foot adapted t0 descend upon and adjust the forming pile, and means :Eorl returning the pressure device into its 'initial position.

.In testimony whereof I aix my signature in presence of two witnesses.
